Support dynamic parameters for OFFSET function

[sequba]

Description

The goal of this task is to remove all limitations of the OFFSET function:

• dynamic parameters e.g. =OFFSET(A1, F16, F17)
• passing range as first parameter e.g. =OFFSET(A1:B1, 0, 0)
• printing OFFSET as a result of getCellFormula
• other limitiations that migh be discovered

Implementation

OFFSET function is hardcoded in HF parser but it should be treated as a regular function. Big refactor is needed for that.
